Formula used
- Assessed Value = Property Value × Assessment Ratio, unless an override is entered.
- Equalized Assessed Value = Assessed Value × Equalization Factor.
- Taxable Value = max(Equalized Assessed Value − Exemptions, 0).
- Base Property Tax = Taxable Value × Local Tax Rate.
- Annual Property Tax = Base Property Tax + Annual Special Assessments.
- Transfer Tax = Purchase Price × Transfer Tax Rate.
- Closing Tax Cost = Transfer Tax + Recording Fee.
- First-Year Prorated Tax = Annual Property Tax × (Ownership Months ÷ 12).
- Total First-Year Tax Cost = First-Year Prorated Tax + Closing Tax Cost.
- Effective Annual Tax Rate = Annual Property Tax ÷ Property Value × 100.
- Five-Year Projection = Sum of annual tax estimates using the selected growth rate.

Frequently asked questions
1. What does this estimator calculate?
It estimates assessed value, taxable value, annual property tax, monthly escrow, transfer tax, closing tax cost, first-year prorated taxes, and five-year projections.
2. Why is purchase price separate from property value?
Many jurisdictions assess taxes from assessed or market value, while transfer taxes usually depend on the transaction price recorded at closing.
3. What is an assessment ratio?
The assessment ratio is the share of market value used to create the taxable assessed value. Some areas assess at full value, others much lower.
4. When should I use the assessed value override?
Use the override when your notice of assessment lists a specific value that differs from the value produced by the local assessment ratio.
5. Do exemptions always reduce taxes directly?
Usually exemptions reduce taxable value first. The final tax savings depend on the tax rate and whether the exemption applies before equalization.
6. Are special assessments recurring or one-time?
They can be recurring annual charges or temporary district costs. Enter the annual amount you expect to pay during the property’s normal tax cycle.
7. What does the five-year projection assume?
It assumes annual property taxes change by the same growth rate each year. Actual taxes can vary with reassessments, caps, levies, and exemptions.
8. Is this a substitute for an official tax bill?
No. It is a planning estimator. Confirm exact rates, equalization rules, exemptions, and closing charges with local authorities or a qualified professional.
